Solving Second order ODE Equation which represents the equation of motion of a simple pendulum with damping using Matlab

Objective: Aim: The Aim is to write a code that solves the second order ODE which represents the equation of motion of a simple pendulum with damping and to simulate the motion of a pendulum for 0-20 sec for angular displacement=0, angular velocity=3 rad/sec2 at time t=0. Finally, an animation video of the motion of…
